I'm trying to create Dropdown button using Bootstrap 5, but I'm getting an error:
Uncaught TypeError: t.createPopper is not a function
This is my HTML code:
<div class="dropdown">
<a class="btn btn-secondary dropdown-toggle" href="#" role="button" id="dropdownMenuLink" data-bs-toggle="dropdown" aria-expanded="false">
Dropdown link
</a>
<ul class="dropdown-menu" aria-labelledby="dropdownMenuLink">
<li><a class="dropdown-item" href="#">Action</a></li>
<li><a class="dropdown-item" href="#">Another action</a></li>
<li><a class="dropdown-item" href="#">Something else here</a></li>
</ul>
</div>
These are the scripts I am using:
<script src="assets/scripts/vendors/jquery-3.5.1.min.js"></script>
<script src="assets/scripts/vendors/popper.min.js"></script>
<script src="assets/scripts/vendors/bootstrap.min.js"></script>

You can use bootstrap.bundle.min.js or bootstrap.bundle.js as an offline library which contains Popper.
Ex:-
<script src="src/jquery-ui.min.js"></script>
<script src="src/bootstrap.bundle.min.js"></script>
This solved my problem. Hope this helps someone.
Your code is working but probably the Bootstrap or the Popper Library is not complete, try using CDN instead of the offline library.
The official documentation of Bootstrap.
